QUICK-RELEASE IVEEANS FOR LOOSE-LEAF BOOKS.

Application filed October 27, ,1921. Serial No. 510,868.

To all whom it may concern:

Be it known that I, Gnomes W. NEWMAN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Quick-Release Means for Loose-Leaf Books; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of refer ence marked thereon, which form a part of this specification.

This invention relates to loose leaf books of the ringbook type in which a plurality of ring members are adapted to be simultaneouslyopened and closed for receiving and re taining the loose leaves, such as are illustrated in the patents to Pitt, Nos. 778,070 and 806,913.

it is an object of this invention to generally improve the construction of such binders and provide a. novel mechanism for operating the ring members, that is effectively concealed and does not destroy the appearance of the book.

With these and other objects in view which will become more apparent in the following description and disclosures in the drawing, my invention comprises the novel features of construction and mechanisms hereinafter described and more particularly pointed out and defined in the appended claim.

In the accompanying drawings which illustrate a preferred embodiment of my invention and in which similar reference numerals: refer to similar features in the different views:

Figure 1 is a fragmentary end elevation of a loose leaf binder to which my invention is adapted.

Figure 2 is a. transverse fragmentary sec-- tion illustrating the ring members in locked position within the loose leaves.

Figure 3 is a fragmentary view illustrating the ring members: in open position.

Figure 4 is a fragmentary longitudinal section through the back of the binder.

Figure 5 is a fragmentary front plan View of the. ring members and frontal plate.

Figure 6 is a plan view of the ring members and plates to which they are secured.

Figure 7 is a fragmentary transverse section illustrating an anchoring means that may be used.

In the accompanying drawings, I have illustrated a suitable book to which my invention may be applied, the same comprising the sides or covers 1 and flexible back 2 which may consist of a. single piece of leather or the like. The leaves are adapted to be removably secured in said book by ring members anchored to the inner side of the back 2.

These ring members comprises series of spaced and rigid arciform wires or hook members 8 suitably anchored to a ring plate 5 and an opposed series of similarly spaced and rigid arciform wires l likewise anchored to an adjacent ring plate 5. The upper or meeting ends of these wires or hook members are provided with the usual interfitting tongues and grooves to securely retain them from relative lateral movement when in locked position.

The inner abutting edges of these ring plates are provided with notches for receiving the shanks of'double headed fasteners or rivets 6 which hold the plates sufiiciently loose forconjoint upward or downward tilting movement in their abut-ting plane, whereby the "ring members are opened or closed. Tie upward tilting movement is effected by a pair of push buttons 7 loosely anchored between said plates or in their abutting plane and extending through the spring plate 8 and anchor plate 15 to the back of the cover of the book, being thus wholly within the book and concealed. These push buttons "are preferably mounted near the ends of the book, and they are pro vided at their inner ends with opposed annular shoulders formed by a groove or reduced portion 7 which {its in circular notches in the abutting edges of the plates 5. The annular shoulders are suliiciently spaced to allow conjoint upward and downward tilting movement of said plates in their abutting plane. The length of these push buttons 7 is so designed that when said plates are tilted upwardly, the spring plate 8 can be assembled as will later appear.

The ring plates 5 are yielding-1y held in abutting relation by means of a spring plate 8 which is slightly concaved downwardly and provided with inturned flanges 9 upon its lateral edges adapted for receiving the outer edges of the ring plates 5 by a sliding movement thereof. These ring plates thuswise supported can be deflected upwardly or open the ring members. In order to provide vided with inturned flanges 13 for improv- V V (provided a novel andeffectiveway of se;

ing the appearance of the book. i

r The assembled device comprisingthe op -i positely bowed plates 8 and 10 and thering plates 5 comprise a unit which is anchored to the inner surface of the back 20f the binder in any well known way. In the drawing, I have shown an inner lining let glued tothe inner sides of the covers, and extendingaround the spring plate 8, and a back plate 15 anchored beneath said lining. This back plate may be interlocked with the spring plate 8 by mutually engaging tongues 16 and sockets 17 as shown in Figure 7.

lVhen the ring members are in closed position as shown in Figure 2, the push buttons Textend. through the spring plate 8, lining Y l4: and back plate 15 which are provided with suitable apertures for this purpose, and

in this'position locks them from relative lonv gitudinal movement. It is possible to spread or open the ring members by pressing in-' ward ly on the buttons through the back of the cover, and forcing theprqjections? up- -w ardly for deflecting or tilting the inner edges of the ring plates 5 in an upward direction as shown in Figure 3. As the push buttons 7 -simultaneously engage both ring plates near, theinner abutting edges thereof,

but little force is required to deflect or tilt i them upwardly, and this force will always lopsided the book may become.

-I am aware that numerous details of con;

struction may be varied through a wide range without departing from the principles I V of this invention, and therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.v
